Integrated pest management and supply chain improvement for mangoes in the Philippines and Australia

This project will incorporate two strategies for improving industry sustainability in the Philippines and Australia: (a) developing improved field management and quarantine monitoring and detection of mango pests and diseases; and (b) working with selected mango supply chains to identify and test areas for improvement.

Alternaria Fruit Spot: New Directions

This project determined the identity of causal pathogens, epidemiology and disease cycle of Alternaria leaf blotch and fruit spot in Australian apples and provided a management strategy for both diseases for inclusion in the integrated fruit production manual.

Alternative fruit fly management for market access for apples

Difficulty with control of Queensland fruit fly with four cultivars of apples on the Granite Belt, Qld. Warnings that the insecticides dimethoate & fenthion might be removed from the market for apples, had been current for several years. Dimethoate was widely used as a post harvest control measure as well as an in-field treatment. Fenthion also had and still has in-field usage. The project attempted to find a replacement for these control measures.

Development of commercial application of an avocado fruit robustness test

Fruit quality is one of the major factors limiting growth in avocado retail sales. Avocado growers are often unaware of their end-use fruit quality since quality problems only manifest upon fruit ripening and growers receive limited feedback from the supply chain. If growers were aware of their expected fruit quality they would be equipped to make better marketing decisions and if necessary to take remedial actions to improve their fruit quality. Avotest is being developed as a quick and easy method of determining expected end-use fruit quality before the start of the commercial fruit harvest. The test aims at distinguishing between blocks with robust fruit and those with less robust fruit. The test could also be used to predict the resulting fruit quality after the implementation of new farming practices.

CRC40088 Pre-harvest for Fruit Fly

CRCNPB funded project aimed to develop improved pre-harvest control strategies for Queensland fruit fly based on autecology and behaviour.

AV08000 Avocado rootstocks improvement

The avocado industry has supported the development and evaluation of new rootstocks for Hass and Shepard avocado. Field sites containing various rootstock/scion combinations have been established around Australia. This project will evaluate tree, fruit yield and and postharvest fruit quality attributes from these field sites.

Improving information for the macadamia industry via an information "bank"

Macadamia growers are under increasing pressure to remain viable in an increasingly competitive global market. A key need is quick access to high quality information. Current industry information is poorly integrated, poorly updated, and because it is largely in hard-copy, is difficult to access efficiently. With the dramatic growth in the use of the internet by growers, as evidenced in a recent industry communications survey, an opportunity exists to address this problem through the development of a high quality, internet-based information “bank”. The bank would bring together the macadamia information resources and collective knowledge of R&D and other relevant agencies into a one-stop information shop, aligned more effectively with grower needs.

Investigating use of irradiation for disinfestation on Custard Apples

The ability to access new international markets particularly New Zealand is the focus of this project for the custard apple industry. Custard apple require a fruit fly disinfestation treatment to access New Zealand markets. Irradiation has shown to be an effective treatment in other fruits and has the potential to be introduced in a relatively short time frame. The project will assess the effect of irradiation on the quality and storage life of custard apples simulating an international supply chain.

Early season replacement for Imperial Mandarin CT09014

Imperial mandarin is the dominant variety in the early season production time slot in Australia. It is well known to consumers, wholesalers and supermarkets, and growers continue to make new plantings of this variety. Despite this popularity, Imperial has major faults that cause problems for growers, consumers, and at other points along the supply chain. Fruit of the variety can be severely granulated, and this is the main quality problem cited by consumers. A second problem with Imperial is its unsuitability for export. Thirdly, the variety has low juice and sugar content, and develops poor colour under warm conditions. We propose a hybridisation project to specifically address these industry obstacles.
